I’m a native Chinese translator having helped a lot of businesses enter Chinese market. I’m a top rated translator with 100% Job Success Score on Upwork. Over the past 3 years I’ve been dealing with translation work in various fields such as business, finance, literature, engineering, education, sports, tourism and so on. I used to be a Java programmer, so I have great advantage in website and application localization. When I translate, I will preserve the meaning, idea and style of the original. I always review my translation carefully at least twice to make it look just like it was originally created in Chinese. For me, translation is an art, I care about my works. I work as a full-time freelance translator and have 40 hours available per week, that’s why I prefer long-term projects. My quality is also different from that of a part-time freelancer. I provide support for my translations for 1 year. As a qualified and professional English-Chinese translator, I’m enthusiastic, responsible, efficient, and I take every job serious.
